Welcome to the all new Tagdef!


It is finally here!  The all new Tagdef!  We’ve rebuilt Tagdef from the ground up to increase speed, functionality and create a simple, more intuitive interface.

We encourage you to login and become a Tagdef member (it is free!).  You’ll get some additional perks like a live timeline of top tweets based on which hashtag you are currently viewing, as well as achievements and credit for any hashtag or definition you add.


We are still working out some bugs and there are still some features from the old site that have not been added back in yet, but over the coming weeks, we’ll be launching those in addition to more new features to help you get even more information about your favorite hashtags and how they can change the way you interact with your audience.

Until then, let us know what you think!


The Tagdef Team

Coming Soon….an all new Tagdef!


You already know Tagdef as the premiere source of hashtag definitions online. In the coming weeks, you’ll see an entirely new interface, more useful features, and tools to help online content creators better understand their audience and find out what is happening locally and globally.

Talk to you soon!
